METHOD OF EXTINGUISHING FIRES.

Specification of Letters Patent.

Patented Aug. 3, 1915.

Application filed November 8, 1913. Serial No. 799,898.

To all whom it may concern:

Be it known that I, JOHN G. FAGAN, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented new and useful Improvements in Methods of Extinguishing Fires, of which the following is a specification.

The object of my invention is to provide a method of extinguishing the flames of burning oil.

In the accompanying drawing, the figure is a side view, parts being shown in vertical section, of my improved apparatus.

Referring to the drawing, on a vehicle 1 having wheels 2, is carried a motor 3 having a pulley 4:, around which passes a. belt 6, passing also around a pulley 7 of a centrifugal blower 8 on said vehicle. The inlet of said blower is connected by a pipe 9 with the lower portion of a box or container 11, containin saw-dust, pulverized cork, or other light substance re uced to e orm of a powder. By the action of the blower the pulverized light substance contained in the box 11 is drawn up through the pipe 9 and discharged through the outlet pipe 12 of the blower. In said outlet pipe is located a nozzle 13, having the same direction as that of the outlet pipe, and communicating by a tube 14:, and flexible hose 16 with a tank 17 containing liquid fire-extinguishing means, such as sulfuric acid and bicarbonate of soda, and provided with the usual valve mechanism by the operation of which said liquids are caused to commingle. For extinguishing an oil fire the blower s set 1n motion and the valve mechanism 1s operated. Saw-dust or other pulverized light material which can float on the surface of 011 is drawn up by the blower and expelled with great force through the outlet pipe and at the same time by the pressure of the gases generated by the mixture in the tank 17, the fire-extinguishing liquid is expelled with great force. The fire extingulshmg liquid is thus sprayed upon the pulverized light material, the particles of which are thus coated with the liquid before being discharged on to the burning oil. When the light material, so coated, falls upon the surface of the oil, it floats thereon, and the fire-extinguishing liquid gives of]? the necessary vapors to extinguish the fire.

I claim The method of extinguishing an oil fire which consists in discharging on to the surface of the burning oil material in the form of powder and lighter than the oil and coated with a fire-extinguishing liquid.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

JOHN G. FAGAN.
